Van Dyk was again a dominant figure as she helped lift Waikato-Bay of Plenty Magic to a 48-39 victory in Invercargill.
The long-time Silver Ferns star has now lauded over Southern Steel in four ANZ Championship matches, and before tonight she had posted an incredible 136 goals against that franchise from 136 attempts.
But the unthinkable occurred during the second quarter tonight when van Dyk inexplicably missed an attempt for the very first time against the Robyn Broughton-coached Steel.
She was to be inaccurate with another three attempts before completing the match with a highly satisfactory 29 from 33, or 88 percent.
It was a minor victory for Southern Steel in the wider battle won convincingly enough by New Zealand's best franchise, who improved their season's track record to seven wins from eight matches.
The southerners remain in fifth place on eight points and retain their semifinals hopes after eight rounds.
But on the evidence of tonight's performance they have much work to do to lift their game to match the top sides.
The Magic made much the more clinical start as they eased out to a 15-10 advantage by the first break, a lead extended to 25-17 by halftime as the visitors put up six more shots at goal.
The Steel stirred to life in the third quarter, upping their physical intensity to peg the difference back to four as a parochial crowd found its voice.
But the Magic are considered best trans-Tasman title hopes for a good reason and they regained their poise to control possession as well as the latter stages of the quarter.
The visitors entered the last break ahead 40-29 and the final result was obvious to all but the most one-eyed of Steel supporters.
Their slim hopes were not helped by the loss of captain and wing attack Adine Wilson in the last period when she aggravated a calf injury, forcing Broughton to switch Liana Barrett-Chase from centre and introduce Wendy Telfer.
Magic skipper Joline Henry singled out defender Casey Williams, who produced her usual classy and committed performance.
"She was very fired up for today's game and you could see that from the whistle. It's just great to have such a calibre of player out there."
Henry said any win in Invercargill was a good win but the Magic still had areas needing improvement.
"We played well in patches but we're still not happy with our consistency."
Wilson said the Steel at no stage hit their straps in such an important game.
"It sought of felt like very pass took a whole lot of effort just to get there. Magic did a really good job making it feel like that, they set up great on defence and slowed our attackers down."
